barrier - "Colorado" series
the automatic electromechanical barrier,
counterweighted with springs, is the fruit of O&O’s
thirty years’ experience in access control automation
and a close analysis of the end user’s requirements.
K4 is a completely new concept and technically
advanced and is the right answer for controlling
accesses in complete safety where medium to high
traffic intensity is envisaged (condominiums,
companies, camping grounds, etc...).
The quality of the materials used and the strict tests it
is subject to guarantee precision movement and 100%
reliability over time.
bearing structure and pleasant looking, K4 is
easily adaptable to any operating environment.
K4 is an electromechanical barrier counterweighted
with springs and with a built in control unit; it is
suitable for controlling road accesses maximum 4 m in
Solidly made, K4 is anchored to the ground with a
The internal transmission mechanisms make the bar
slow down when opening and closing imparting a
considerable fluidity and precision to movement.
Thanks to an adjustable electronic clutch, both the
thrust force and control of the impact force in the case
of knocking against an obstacle can be accurately
equipped with a Reverser, an anti-crushing
control system that stops the bar immediately if it
comes up against an obstacle, reversing movement.
The barrier can always be operated manually, putting
it in neutral, by means of a key system on the outside.
During maintenance, a micro switch

and mechanical parts in complete safety.
A flashing light, key selector and a photoelectric cell
can be installed directly on the K4’s structure; in
addition, it can be fitted with a round bar and
